Panasonic 4K Tablet

The Panasonic 4K tablet, which runs on Windows 8, was unveiled alongside a 4K OLED TV, and is aimed squarely professionals such as photographers and architects. While it may be out of reach for most of us mere mortals, it's still an interesting piece of kit - here's what we thought.

 The tablet packs an Intel Core i5 3427U vPro processor, clocking in at a speedy 1.8GHz, and you'll also get the benefit of an Nvidia GeForce graphics processor.

There's only 4GB of built-in memory plus 128GB on SSD and there's also a micro SD card slot for topping up the capacity.

Connections are limited to Wi-Fi, Bluetooth 4.0 and a USB 2.0 and there's also a Digital Pen stylus, similar to those that come with Wacom's graphics-focused tablets.

According to Panasonic, you'll get up to two hours of battery life, which doesn't sound like much for a tablet, but then the 4K screen is sure to be pretty power hungry.
